Abstract

L'objet de la présente invention est un système (1) de détection angulaire et de profondeur d'une source lumineuse (2), ledit système (1) comprenant au moins deux dispositifs de photo-détection (6, 7) aptes à détecter un faisceau lumineux (5) en provenance de la source lumineuse (2) au moins une paroi de masquage (8) configurée pour masquer au moins partiellement le faisceau lumineux (5) vis-à-vis des au moins deux dispositifs de photo-détection (6, 7) et des moyens de calcul configurés pour déterminer la position et la distance de la source lumineuse (2) par rapport aux dispositifs de photo-détection (6, 7) par mesure différentielle de la puissance lumineuse reçue par les dispositifs de photo-détection (6, 7), caractérisé par le fait que l'au moins une paroi de masquage (8) est inclinée par rapport au plan de chacun des dispositifs de photo-détection (6, 7).
